MPI_File_read_all_begin(3)            MPI           MPI_File_read_all_begin(3)

NAME
       MPI_File_read_all_begin -  Begin a split collective read using
       individual file pointer

SYNOPSIS
       int MPI_File_read_all_begin(MPI_File mpi_fh, void *buf, int count,
                                   MPI_Datatype datatype)

INPUT PARAMETERS
       fh     - file handle (handle)
       count  - number of elements in buffer (nonnegative integer)
       datatype
              - datatype of each buffer element (handle)

OUTPUT PARAMETERS
       buf    - initial address of buffer (choice)

NOTES FOR FORTRAN
       All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have
       an additional argument ierr at the end of the argument list.  ierr is
       an integer and has the same meaning as the return value of the routine
       in C.  In Fortran, MPI routines are subroutines, and are invoked with
       the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in
       Fortran.
